UNITED STATES PATENT OFFICE.

CHARLES A. FAUSEL, F GLEN RIDGE, NEW JERSEY, AND HARRY E. BAUER, OF NEW YORK, N. Y., ASSIGNORS TO INTERNATIONAL TAXAMETER CORPORATION, A COR- PORATION OF NEW YORK.

INDICATOR.

Application filed November 6, 1923. Serial No. 673,065.

Our invention relates to improvements in ind lea-tors, either singly or in association or combination with a tare registering device, conn-nonly called a. taximeter, and particularly to such devices as are used upon public conveyances, such as taxicabs, for the purpose of distinctly, plainly and visually indicating whether the conveyance is hired or vacant.

'lheinvention is adapted for use with a fare register of the class disclosed in our copeuding application filed September 24;. 1923, Ser. No. 664.361, and that disclosed in the patents to Alonzo G. Decker, No. 1.058222, dated April 8. 1913, and No. 1,013,279, dated January 2, 1912. upon which our improvements are predicated. In this application we have (ilescribed and disclosed only such parts of the mechanism of said application and patents as are essential to a proper understanding of our invention, reference being made to said application and patents for at'nll and complete understanding of the meclr anism which is not covered by our improvement as herein described.

Owing to the great difficulty experienced by the public in ascertaining whether a taxicab hired or vacant. especially in the congested trafiic conditions in the shopping districts in the daytime, and more especially at night, and again during the rainy seasons both day and night. the inconvenience and danger to the public in walking on the driveway t wing to a vacant taxicab, it became ncct [try to devise means of apprising the public as to whether a taxicab is vacant or hired without leaving the sidewalk or shelter in bad weather.

It is one of the objects of our invention to provide an indicator, placed in a conspicuous position on the root of the vehicle, so that it.-

will be readily visible and plainly indicated whether the taxicab is hired or vacant, the indicator being seen from a considerable d istan ce.

Another object of our invention is the construction of an indicator which will be automatic and positive in operation and out of the control or" the driver.

.i'inother object. of our invention is to provide an indicator in combination with a fare registering device and means for simultaneonslv operating said fare registering device and indicator.

Another object of our invention is to pro vide means, automatic in operation at a predetermined point, to take the control of the device out of the hands of the driver.

The operation of taxicabs and the tariff to be charged by such vehicles are now universally regulated by ordinances which vary in extent and condition in various localities, but all such regulations require that the taxicab operator shall indicate whether the vehicle is hired or vacant. A further im portant feature and advantage of our inveir tion resides in the fact that with the indicator in a prominent position on the top of the taxicab, it is readily and easily seen by the police and the inspectors of the operating companv owning the cabs. and they will be thus in ormed as to whether the taxicab is hired or vacant.

With these and other objects in view to be more fully set forth hereinafter, the invention consists in the novel construction. combination of elements, and arrangement of parts for a device of the character described by means which will be exemplified in the operation and construction herein described in the following specification and illustrated in the accompanying drawings, considered together or separately In the 'drawings,

Description and operation of the rotary indicator.

'Aflixed to the base 1, Figs. 2, 3 and 7, are the sides 2, 3, 4 and which are bent up from one piece to form the shape shown, the ends of said piece being firmly held together at the side 5 by a strip 6. 'The sides 2 and 4 have therein openings 7 and 8 (Figs. 1 and clasp 17 and padlock l8,"said padlock being locked in position with a key which is in the possession of the owner of the car. It can be seen that the container made up of the base 1, the sides 2, 3, 4 and 5, and the cover and glass plates 9 and 10, will be tamper-' proof and waterproof and will protect from the elements or molestation any mechanism or parts that might be placed therein.

A bracket 19 is afiixed to the base 1, Figs. 2, 3, 4, and has mounted thereon the magnets and 21 in the spools of which are secured the cores 22, 23. Leading from the magnet 20 are the feed wires 45, 46, and from the magnet 21 the feed wires 47 48. The wires 45, 46 and the wires 47, 48-energize their corree spond'ing magnet when an electric current is passed through them at the proper time. The magnet plungers 24, slide in the spools of the magnets and are secured to the adjustable connections 26, 27 which, in turn, are

held by the pin and slot combinations 28, 29 to the rocker arm 30. The rocker arm 30 is fixed on one end of a shaft 31 which is journaled in the bracket 19. To the other end of the shaft 31 is secured a gear segment 32, Fig. 5, which meshes with a mutilated gear 33 affixed on a hub 34. Hub 34 has affixed thereon a notched disk 35 and is pivotally mounted On a stud 36 secured to the bracket 19. The disk 35 has two notches 37, 38 which are one-quarter of a revolution apart and which engage at the proper time with a roller 39mounted on a stud 4O fixed to one end of a lever 41. A stud 42 is secured to the bracket 19 and has mounted on it the lever 41. A spring pin 42 is affixed to the lever 41 and carries one end of a spring 43, the other end of which is held by a pin 44 secured to the bracket-'19. The spring 43 holds the roller 39 of the lever 41 against the periphery of the disk 35. Thus, when the roller 39 is in engagement with one of the notches 37 or 38, it prevents accidental rotation of the disk 35.

Theoperation of the mechanism so far described-is as follows: Vhen the magnet 20 is energized by an electric current passing through the wires 45, 46, it attracts the plunger 24 which in turn rocks the lever 30 inn/clockwise direction (Fi s. 4, 5). motion is transmitted to thegear segment 32 whichturns the mutilated gear 33 in a counter-clockwise direction one-quarter of a rev olution. The notched disk 35 turns with the mutilated gear 33 and in so doing cams the roller 39 out of the notch 37. When the notched disk 35 nears the end ofits onequarter revolution, the roller 39 is forced into the notch 38 by the spring 43 and this spring retracts the notched disk 35 in the position in which it is finally placed. When the plunger 24 descends, the plunger 25 ascends due to the action of the rocker arm and in so doing places the plunger 25 in a position to actuate the mechanism when the magnet 21 is energized. lVhen the plunger 25 attracted by the magnet 21 it turns the notched disk in a clockwise direction one quarter of a revolution, thus again putting it in the position as shown in Fig. 5, where it is retained by the roller 39.

A rectangular box-like member (Figs.

' 1, 2, 3, 5, 6, 7) has sides 51,52, 53 and 54 and the ends 55 and 56. The edges of the ends 55, 56 are bent and are fixed. to the sides 51, 52 The side 54 is hinged on one of its edges to an edge of the side 51 and swings on a pin 57. The other edge of the side 54 has a bent portion 58 which encompasses the bent edge 59 of the side 53. To hold the side 54 in the position shown, the knobs 60 are rotatably mounted in said side and have attixed thereto the bent members 61 which engage with the bent portion 59 of the side If it is desired to swing the side 54 on its pin 57 to gain access to the interior of the box 59, the knobs 60 are turned, thus disengaging the bent members 61 from the bent portion 59 and so allowing the side 54 to be swung upwardly. The sides 51 and 53 have cut in them the word Vacant and the sides 52 and 54 the word Hired. Mounted on the sides 51, 53, in back of the word Vacant, are the sheets of colored translucent material 62, 63 (Figs. 3. 7), and mounted on the sides 52, 54, in back of the word Hired are the sheets of a ditterent colored translucent material 64, 65. \Vith the sheets of translucent materials of different color, say green for vacant and red for hired, it will enable persons, especially at night, when the indicator is illuminated, to ascertain whether the taxicab or conveyance is vacant or hired, at a great distance, where the indicator would be unreadable by distinguishing the different colors that mightbe presented. In the daytime the colors would be easily distinguishable and the words Vacant and Hired could be seen from a distance.

To the notched disk 35, Figs. 2, 3 and 5, are affixed the pins 70, 71 which protrude into corresponding holes .in the end 55 of the box 50, thus causing the end 55 and hence the box 50 to rotate with the notched disk when it is actuated. The end 55 has a hole 72 which fits over the hub 34, thus pivoting box 50. A hole 73 in the end 56 3, 6, 7) encompasses a hub 7 4 and also serves as a pivot for the box 50. To the hub 74.- is secured a disk '75 upon which are afiixed the pins 76, 77, said pins engaging with corresponding holes 78, 79 .in the end 56. The hub 74 is rotatably mounted on a stud 80 which is fixed in a bracket 81 secured to the base 1. The stud 80 has a passageway 82 through which he wires feeding the illuminating means are led. It can be seen that when the box 50 is rotated the hub 74 will also rotate, due to the connection between the end 56, the pins 76, 77 and the disk 75, thus giving the box 50 a larger hearing surface than it would have it' it turned with the hole 73 of the end 56 as a bearing and so lessening the wear. It can be seen that t-he'holes in'the end 55 through which the pins 70 and 71 protrude are not coincident with the holes 78, 79 in the end 56. Therefore it will-be impossible to put the box 50 in the container so that the end 56 would be where the end 55 now is, and vice versz, because the holes 78, 79 will not register with the pins 70, 71, nor will the pins 76, 77 register with the holes through which the pins 70, 71 protrude. Also, it will be impossibie when setting the box 50 in the container to place it in any position except as shown in Fig. 5, as the pins 70, 71 will not register with the corresponding holes in the end except when the end 55 is in the position indicated.

To the stud 36, Fig. 3, is secured a tubular member 85 which has atlixed thereto a socket 86 into which an electric bulb 87 is placed. Leading from the socket 86 are the wires 88, 89 which, when energized,illuminate the electric bulb 87. The wires 88, 89 are led through a hole 90 in the tubular member 85 and extend through the interior of the box 50 to a hole 91 in a tubular member 92 which is atlixed to the stud 80. A socket 933 is fastened to the tubular member 92 and holds an electric bulb 94 which is energized by the wires 95, 96 and then are led through the passageway 82 in the stud 80 to the proper switching and energizing means. The bulbs 87 and 94 are thus connected in parallel so that when the wires 95, 96 are energized, both bulbs will be illuminated. Two bulbs a re used so as to provide a better distribution of light; also to insure partial illumination of the indicator in case one of the bulbs should burn out.

In Fig. 2 there are shown in the base 1, the holes 99, 100, 101 and 102. These holes are used to retain the securing means which hold the indicator in position on a. taximeter or other conveyance and will be described later. The base 1 is also provided with a hole 103 which secures one end of a means used for leading the wires from the indicator. These means will also be described later.

The operation of the indicator is as follows:

It will be assumed that the indicator is so mounted on the top of the taxicab or conveyance that it will appear a s in Fig. 14 when viewed from the front of the vehicle and that it is controlled by a type of taxinietcr or tare indicator such as disclosed in our co-pending application, previously mentionet. It will be obvious that in the indicator mounted as aforementioned. the word Vacant will be visible through the glass in the side 2 to any from the rear. ll hen the taxicab or conveyance is idle 'or waiting for passengers, the

flag ot' the taximeter will be in a vertical position which will indicate that the vehicle is tor .hire or vacant, and the indicator on the root of the vehicle will also showtVacant, as shown in Fig. 14;, thus making a more obvious presentation of the condition of the vehicle to interested persons. hen a passenger hires the taxicab, the driver turns thewing nut 462 on the back oi the taximeter and starts to lower the flag. JV hen the flag reaches its midway or predetermined position, the automaticcontrol mechanism comes into action and automatically takes the device out of the control of the driver, and sets the indicating and recording mechanism in the hired position, as described in ourco-pend ing application heretofore mentioned, to which reference'is made for a full and complete description of the operation Unereot'. At the same instant, a mechanism, also actuated by the automatic control, closes the circuit of the magnet 20, Figs. l and 5, thus i brating the rocker arm 30, and hence rotating the notched disk35 one-quarter. of a revolution in a c'ounterclockwise direction which, in turn, through the pins 70, 71, imparts a like motion to the box 50, thereby moving the side 52 of said box in the positionthat was formerly occupied by the side 51 and moving the side 54 in the former position of the side 53. The word Hired will thenappear in the indicator, thus informing those interested of the condition of the vehicle; .Nhen the driver sets. the tanimetcr to the cash ortemporary non-recording position to discharge a passenger, the indicator will still show Hired, as the vehicle is engaged until the passenger has paid his fare and left the vehicle. After a passenger has paid his fare, the driver again turns the wing nut on the taximeter, thus raising the flag towardthe vacant position. When the flag reaches the midway or predetermined position, the automatic control again comes into action, thus causing the indicating and recording mechanism of the taxicab tobc set in the .vacant position and also actuatinga mechanism whichcloses the circuit of the magnet 21.'

The actuation of the magnet 21 rotates the box 50 one-quarter otarevolution in a clockwise (l11'QCtlO]1,-tllU.S again causing the indicator to show the word Vacant and hence i nvforming those concerned that the taxicab or cator, thereby making-it impossible for the driver to set the indicator in a false position. The circuit of the lights 87 and 9 1 of the indicator is controlled by a key switch in the taximeter which will be hereinafter described. The key for this switch is held by the owner or operator of the taxicab who can, by turning the lock, cause the lights to be illuminated. This switch is installed so that it will not be necessary for the lights to remain illuminated during the daytime or while the vehicle is in the garage or storage.

As the driver does not have a key for the key switch, it will be impossible for him to extinginsh the lights at any time for any reason whatsoever.

Descriptioaof the motle'ficd indicator.

The casing 120, Figs. 9, 10, 11, 12, 13, consists of the sides 121 and 122, the top 123, the bottom 1% and the ends 125 and 126. The sides 121 and 122 and the top and bottom 123, 12st aretorined from one piece, two edges of which are secured on the bottom 124: by a strip 127. The end 126 is fixed to the sides 121, 122, and theend 125 is secured on the bottom 12 1 by a hinge 128 and on the top'123 by a clasp 129 and padlock 130. A partition 131 is fixed to the sides 121 and 122,'dividing the casing 120 into two light-tight compartments. he side 121, Fig. 12, has the openings 132, 133, and the side 122 the openings 13%, 135. In back of the openings 132, 13 1 are the colored glass pieces 136, 137, behind which are the stencils 138, 139, in which is cut the word Vacant. The glass pieces 136 and 137 and the stencils 138 and 139 respectively slide in the guides 1 10 and 141, fixed to the sides 121 and 122 and the guides 142 and 1&3, fixed to the partition 131. To the rear of the openings 133 and 135 are the glass-pieces 145 and 146 which are of a different color than the glass pieces 136 and 13? and behind which are the stencils 147 and 148 in which is cut the word Hired. The glass pieces 145 and 1 16 and the stencils 1 17 and 148 respectively slide in the guides 149 and 150'fixed to the partition 131 and the guides'151 and 152 fiXedto the sides 121 and 122. As the glass pieces are colored, thewords on the stencils will not show through them unless a light is placed behind the stencils. It can then be seen that if a light is placed behind the"Vacant stencils 138 and 139 and none behind the Hired stencils 147 and 1 18, the word Vacant will appear in the openings 132 and 13e whereas the openings 133 and 135 will remain blank construction of the casing'1'2y0, itis obvious the top 123 and the bottom 12%,

that said casing is tamper-proof and any parts that are contained therein would be protected from molestation. Any attempt by a driver to gain access to any oi the parts con tained in the casing would be detectable, as to do so, he would have to noticeably damage the casing. This will insure against tampering as the driver would have to account for any meddling that might be done on the casing.

Means are also provided for illuminating the .upper and lower or vacant or hiredi compartments of the indicator. In the upper compartment, the electric bulbs and 161, Figs. 10, 11. 12, 13 are mounted in the sockets 162 and 163, fixed to the partition 13 The bulb 160 is energized through the wires 16-1-and 165. secured to the socket 162, and the bulb 161 is energized through the wires 166 and 167 secured in the socket 163. The wires 161 and 166 and the wires 1 65 and 167 are connected to each other, thus placing the bulbs 1 60 and 161 in parallel and causing both to light when the wires are properly energized. In the lower compartment the elec tric bulbs 168 and 169 are mounted in the sockets 170 and 171. fixed to partition 131. Held in the socket 170 are the wires 172 and 173 which energize the bulb 168. he wires 174 and 175 are connected to the socket 171 and energize the bulb 169. The wires 172 and 17 4c and the wires 173 and 175 are electri ally connected to each other, putting the bulbs 168 and 169 in. parallel, thereby causing simi-zltaneous illumination of the same. are used in each compartment so as to secure a better distribution Off light and also to insure illumination in case one of the bulbs should burn out.

Means are also provided to prevent the seepage of a strong external light through the glass and stencil of an unlighted compartment on to and through the stencil and 0t the opposite side of the comparh ment, thereby, especially in the daytime, preventing confusion in reading the indicator. In other words, these means insure that the word in the opening of the illuminated com partment will be the only word visible irrespective of any effect that an external light would have on the unlighted compartment. 1 s embodied in Figs. 10, 11, 12 and 13, the shields and 181 are placed in the center of the upper and lower compartments respectively, thus preventing the passage of light from one side of a compartment to the other side. It is therefore apparent that ii light from an external source should pass through the glass and stencil ot' a side oi an unlighted compartment, it will strike the shield which would prevent it from reaching opposite side of the compartment and therefore it would have no effect on the stencil and glass of said opposite side of the compartment. Also, the word on the side of the un- Two bulbs lighted compartment through which the external light is passing would not show as a light from the interior ol the compartment must be thrown on the stencil before the word will appear in the opening of the indicator. The shields 180 and 181 are provided with openings 182 and 183, Fig. 11, which allow the light from the bulbs 160 and 168 to illuminate both sides of their respective compartments. Like openings are also provided in the shields 180 and 181' for the lights 161 and 169, but are not shown as the shield is broken away in the portion referred to. Covering the portion of the openings 182 and 183 nearest to the partition 1 31 are the formed pieces 185 and 186 fixed to the shields 180 and 181. These formed pieces 185 and 186 are bent to clear the sockets 162 and 170 and are used to prevent light from passing through the openings in the shields caused by the presence of the sockets. Similar formed pieces are used to cover the openings in the shields due to the sockets 163 and 171, one of said formed pieces being shown in plan in Fig. 10. The shields 180 and 181 are made renmvable so th at the lights 160 161 and 168, 169 can be renewed. In Figs. 10 and 11 said shields have rotatably mounted thereon the knobs 187 to which are aiiixed the bent arms 188 which engage with one leg of the angle pieces 189 fixed to the top 123 and the partition 131 and also with one leg of the angle pieces 190 secured to the bottom 121 and the partition 13].. If the shields 180 and 181 are to be removed, the knobs 187 are turned until the bent arms 188 are out of engagement with said legs of the angle pieces 189 and 190, thereby allowing the removal of said shields.

Means are further provided for securing the indicator to the taxicab or conveyance and also for securing the wire leading means to the same. Fixed to the bottom 124 of the casing 120, Figs. 10 and 11, are the reinforcing pieces 200 and 201 in which are the holes 202. 203, and 20 1, 205 respective In the piece 200 there is also formed an opening 206. The holes 202. 203, 204 and 20? extend through the bottom 121 and are used to retain bolts which secure the indicator to the vehicle. The opening 206 also extends through the bottom 124 and is used to retain a wire leading means fixture. Figs. 16 and 17 show the application of the means for securing the indicator to the taxicab and the wire leading means to the indicator and taxicab. In Fig. 17, the bolts 207 and 208 extend through the roof of the vehicle 209 and the holes 202, 203 in the reinforcing pieces 200 and the bottom 12 1. The bolts 207, 208 have mounted thereon the collars 210, 211 and the washers 212, 213 which space the indicator a fixed distance from the roof of the vehicle 209 so tha the end 125 may be opened without strikin said root. The Hilts 214, 215 and the chcl nuts 216, 217

on the bolts 207,208 securely hold the indicator in its fixed postion on the rootof the vehicle. As the nuts which secure the bolts are on the inside of the container ofthe indicator and the construction of the bolt heads is such that it is impossible to .withdraw the bolts unless thenuts are removed,it can be seen that it is impossible-for a driver to tamper with-the securing means. In Fig. '16 is shown the means for securing the wire leading means fixture 220 to the vehicle and indicator. The fixture 220 is of tubular construction and is formed to shape an elbow, one end 221 being threaded and the other end 222 having secured thereto a tubular member 223 through which the wires feeding the lights are led. The fixture 220 has ashoulder 224 which engages the fixture 220 to the roof as shown when the washer 225 and the nut 226 are placed in position. The threaded end 221 of r the fixture 220 extends through the vogening 206 in the reinforcing piece 200 and the bottoin'124. The washers 227, 228 encompass the threaded end 221, and the nuts 229, 230 securely hold the indicator, the fixture 220 and the washers 227, 228 in place. asshown. From the construction shown, it is obvious that it is impossibleto withdraw thefixture 220 fronithe root of the vehicle or'the indicator unless one has accessto the interior of the indicator to unfasten the nut 230. As the indicator is locked and only the proper parties have access to its interior, it can be seen that'the fixture 220 cannot be Withdrawn by the driver or other molesting persons so as to tamper with the wires contained therein. In Fig. 11 there is shown in the shield 181 an opening 231 which is directly'over the fixture 220 and is formed so as to clear the wire and connection-plug which issue from said fixture. The means used for securing this modified form of indicator and the fixture 220 to the. root of avehicle can also be used for securing the rotary indicator and its wire leading means to said roof in a like manner. In Fig. 2 the base 1 of the rotary indicator is shown provided with the holes 99, 100, 101, 102 used for retaining the bolts which secure said indicator to the roof of a vehicle, the construction being similar to that shown in Fig. 17. The opening 103 in the base 1, Fig. 2, is used to retain a fixture of a construction, as shown in Fig. 16, for leading wires to the interior of said indicator. I r

The modified-form of indicator operates as follows: It will bezassumed that the indi-.

Vith the bulbs 160, 161 areilluminated. When the taxicab or conveyance is hired, the driver turns the wing nut on the back of the taxiineter, thus lowering the flag. l/Vhen the flag reaches its midway or predetermined position, the automatic control comes into action and automatically, out of the control of the driver, sets the indicating and recording mechanism of thetaxinieter in the hired or recording position, all as fully described in our co-pending application hereinbetoro mentioned. the automatic control also actuates amechaiiism' in the taximeter, which extinguishes the bulbs 160, 161, and illuminates the bulbs 168, 169 in the indicator, thus causing the word Vacant .to disappear from the open ings 132, 134: and the word Hired to appear in the openings 133, 135. \Vith the iiidicator so mounted on the top of the taxicab or conveyance so that it appears from the front of the vehicle as shown in Fig. 9, it is evident that the COnClltlOIl of the vehicle,

Simultaneous with this setting 7 whether vacant or .liired, will be readily discernable at'a distance from either the front or rear by reading the word which V T L appears in the openings. When ihe driver discharges a passenger, he turns the w ng nut on the taxiineter and the. automatic control sets the indicating and recording mechanism of the taximeter in a cash ortein-' porary non-recording position. During this operation theindicator open ngs'133, 135 still show Hired and the openings 182, 13 1- still 7 remain blank as the vehicle is hired until the passenger pays his fare. When the passenger has paid his fare, the driver again turns. the wing nut thus raising the flag and 168, 169and illuminates the bulbs 160, 161

of the indicator, thuscausing the openings 133, to be blank and the openings 132, 131 to register Vacant. It is evident from the 'i oregoing descriptionthat the indicator is controlled from thetaximeter aiidas said taximeter is out of the control of the driver, due to the automaticcontrol it is obvious that at no time can the driver govern the functioning of the indicator so that it will show a false reading. r

The circuit of the bulbs 160, 161, 168, 169 has a key switch which'is mounted in the taxinieter and which is used to shut oil the supply of electrical current from the bulbs when the vehicle is not in use, that is, vhen it is in the garage or storage. The owner or operator of the taxicab or conveyance has possession of the key for the key switch and, therefore, the driver can at no time extinguish the bulbs. The operation of the key switch will be described later. In this type of modified indicator it is cvidentth'at either Vacant or Hired must at all times, while the vehicle is in operation, appear in the indicator and, therefore, if either of the words does not appear, it would be obvious that, unless the bulbs were burned out, the driver was tampering with the system, and in that case he could be made to account for any molestation.

Mechanism for controlling the rotary indi- Gator.

To the main plate 250 of the taximeter, Figs. '18, 19, 20, is aflixed a stud 251 upon which are rotatably mounted two armed levers 252, 253, said levers having arms 25 i, 255 provided with pieces of insulation 256, 257 to which are secured the electrical con ducting blades 258, 259. The other arms 260, 261 of said lovers have ailixcd thereon the studs 262, 263 upon which are mounted the rollers 264:, 265 which coact with the cams 266, 267 secured on a hub 268 atiixed to the cam shaft 269. The arms 260, 261 are spring retained in the position shown by the springs 270, 271 the ends of which are secured to said levers and to the studs 272, 273 aifixed to the bracket 274 mounted on the main plate 250. Pivot ally mounted on the stud 275a-re the dashpots 276, 277, the piston rods 278 of which are secured 'to the arms 260, 261 of the levers 252, by the pin and slot connections 286, 281. The upper end of the piston rods 278 ha vc affixed thereto the usual form air valve and piston comprising leather and metal washers. The portion of the dash pots 2'76, 277 above the pistons, have small holes which regulate the escape of air from the dash pots. W'hen the dash 'Jots 276, 277 are actuated by adownward movement of the arms 260, 261, air is drawn into the upper part of said dash pots and imprisoned there by the pistons. The return of the arms 260, 261 and hence the levers 252, thus retarded; their return depending on the length of time it will take the SPIlHgS 270, 271 to force the air in the upper portion of dash pots to escape through the holes therein. The purpose of retarding the return of the levers 252, 253 will be here-- inafter described.

Mounted on a block of insulation 280, aflixed to the bracket 27%, are the springs contacts 281, 282 and 283, 284 (see also Fig. 8), which are held in position by the fastening means 285, 286 and 287, 288. The fastening means 286, 288 and, therefore, the spring contacts 282, 284, are electrically connected by the bus 289 from which a wire 290 is led. The spring contacts 281, 283 are electrically connected to a remote source by the wires 291,

292, secured to the fastening means'285, 287.

Thus, when the conducting blade 258 is moved into engagement with the spring contacts 281, 282, the electrical circuit between the wires 290, 291 will be completed and in a like manner when the conducting blade 259 moved into engagement with the spring contact. 284, the electrical circuit between the wires 290 and 292 is completed. Said conducting blades are moved into engagement with said spring contacts when the lobes 29 i. of the cams 266, 267 coact with the rollers 261-, 265 on the arms 260, 261, thus causing the levers 252, to swing in a clockwise direction.

The operation of the mechanism just described is as follows It is understood that the cam shaft 269 makes one-third of a revolution every time the automatic control actuates it. Vhen the cam shaft 269 makes the first third revolution (starting from the position in F ig. 18), the lobe 29st of the cam 266 strikes the roller 26 1 of the arm 260 thereby causing the lever to rotate in a clockwise direction, thus engaging the conducting blade with the spring contacts 281, 282 which closes the circuit of the wires 290, 291 and hence energizes the magnet 20, shown in Fig. 5': and so causing the rotary indicator to show Hired, which is also the position that the indicating and recording mechanisi'n of the taximeter is set in. by this first one-third revolution of the cam shaft 269. T ie construction of the lobe 291 is such that it will be entirely out of the path of the roller 26% when the cam 266 has completed its first one-third revolution so that the lever 252 may return to is ori inal position. As the cam shaft 269 is spring actuated by the automatic control, it obvious that unless some retarding means were afiixed to the lever 252 the conducting blade would make and break its engagement with the spring contacts 281, so quickly that the magnet 20 would not be sufficiently energized to actuate the indicator. 'lhereforc, the dash-pot- 276 is secured to the lever 252 and retards the motion of the conducting blade 258 so that it stays in engagement with the spring contacts 281, 282 long enough to sullicientl y energize the magnet 20 to allow it to perform its function.

The second one-third revolution of the cam shaft 269 sets the mechanism of the taximeter in the cash or temporary non recording position. During this portion of the revolut on neither the lever 252 nor the lever is actuatechthus leaving the indicator in the hired position. However, on the third onethird revolution of the cam shaft 269. which places the taximeter mechanism in the vacant position, the lobe of the cam 267 strikes the roller 265 of the lever 255, thus causing the conducting blade 259 to engage with the spring contacts 283, 284C. hence closing the circuit of the wires 290, 292 which ext-- ergizesthe magnet 21 thereby causing the indicatorto show Vacant. The dash pot 277 retards the return of the lever 253, thus allowing sufficient time of engagement between the conducting blade 259 and the spring contacts 283, 284 tov properly energize the magnet- 21. i

A key switch is also mounted in the taximeter to control the bulbs 87, 94 of the rotary indicator. In Figs. 19, 20, 21 and 22 a lock300 is held in a bushing 301 affixed to V the back plate 302. A dust cap 303 is pivdirection before it can beremoved. turning of the key rotates the barrel 306 and oted on a pin 304, secured in the bushing 301 and prevents the entrance of foreign matter into the key slot- 305 of the barrel 306 in the lock 300. The barrel 306 has affixed to its other end agear 307 which engages with a gear 308 mounted on'a stud are securedto the extensions 317, 318 of the spring contacts 313, 314 thus electrically connecting said spring contacts to a remote source. The spring contacts 313, 314 are mounted on the insulation 319 atfixed tothe main'plate'250. When a key is inserted in V the slot 305' of the lock 300 and turned,it must be turned one revolution, in either This hence the gear 307 one revolutionthereby causing the gear 308 to turn one-half revolution, thus disengaging the conducting blade 312 from the spring contacts 313, 314 which breaks the circuit-of the Wires 315, 316, causing the bulbs 87 94 in the rotary indicator to be extinguished. Further turning of the key will again engage the conducting blade 312 with the spring contacts 313, 314, thus again illuminating the bulbs 87, 94. The key for the lock 300 is held by the owner or operator of the taxicab and therefore the driver has no control whatsoever over the operation of the illuminating means of the indicator. The bulbs 87, 94 are only extinguished when the taxi,- cab is not in operation, tl'iat is, when it is in storage or in the garage; Means are pro- .vlded for leading the wires in the taximeter tojan outside source. As embodied in Figs. 20, 21 and 26, a switch plug 330 has a female insulation member 331 fixed to the main plate 250 and the clock mechanism plate 332 and also amale insulation member 333 extending in the opening 334 of the ta-Ximeter case 335. The female insulation member 331 has mounted therein the electrical: contacts 336, 337, 338, 339 which engage with the electrical contact-S340, 341, 342, 343, mounted in the male insulation member .33. It will be noticed that there is a greater space between theelectrical contacts 338 and 339 mounted in the female insulation member 331 than between the electrical contacts 337, 338 and 336, 337, and that a similar formation is embodied in the electrical cont-acts 3,40, 341, 342, 343 mounted in the male insulation member 333. This formation is so arranged that it is impossible'when engaging the male and female members to placethem in any position except as shown, thereby preventing any possibility of accidentally engaging them in an incorrect manner and change the 'wiring of the'circuit. .The electrical contacts 336, 337, 338, 339 have respectively affixed thereto the wires 291, 292,290, 315 which have been heretoforedescribed. Secured to the electrical contacts 340, 341, 342, 343' are the wires 344, 345, 346, 347 which are clamped to the male insulation member by an insulation strip 343, thus insuring said wires from being disengaged from-said 616C? trical contacts when the male insulation member 333 is withdrawn from thefemale insulation member 331. The wires 344, 345, 346, 347 extend through an elbow 350 which secured to abracket -351' by a nut 352. To the elbow 350 is affixed the tubular member 353 through which said wires are led to a remote source.

The bracket 351is affixed to aportion of the frame of the taxicab or conveyance and carries the taximeter. The taximeter is secured to thebracket 351by the-screw fastenings 354, 355 extending throu h said bracket and the case 335. The screw fastening 355 is sealed by a seal 356 thus preventingthe removal of the taximeter from the bracket 351 by improper parties and hence securing from molestation-the wire leading means 350, 353whichcannot be removed unless the taximeter is. taken off said bracket. The slack shown in the wires344, 345, 346., 347,

as they enter the elbow is due to the extra.

length of wire needed when inserting the male member 333 of the switch plug 330 into the-female member 331. Fromthe constructionshown, it isobvicus that both the taximeter and the wireleading means are so mounted that it is impossible for the driver to tamper with them without being detected.

' 373,. 374fand are held, at their other ends by the studs 383, 384 mountcd'on bracket 385, affixed to the main plate 250. The springs 381, 382 retain the rollers 377, 386 against the HMS 379,380 and tend to swing the levers 371, in a eonliter-clockwise direction. The other arms 387, 388 of the two armed levers 371, 372, have affixed thereto the insulations 389, 390, to which are secured the electrical conducting blades 391, 39 which enc respectively with the elect wal spring cts 393, 394 and 395, 396. The spring cts 393, 394 and 395, 396 are held by the ing means 397, 398 and 399, 400 to a block of insulation 401, affixed to the bracket A bus 402, held by the securing means 397, 399, electrically connects the spring contacts 394. 396 together and a wire 403 is led therefrom to electrically connect said spring contacts to a remote source. The securing means 398, 400 have affixed thereto the wires 404, 405 respectively. which electrically connect the spring contacts 393, 395 to a remote source. The cams 379, 380 have the lobes 407, 408 which when in engagement with the rollers 376, 378, swing the lovers 371, 372 in a clockwise direction, thereby throwing the conducting blades 393, 394 into engagement with the spring contacts 393, 394 and 395, 396, thus closing the circuit of the wires 403, 404 and 403, 405. The roller 378 is shown in engagement with the lobe 40S. theraiy causing the conducting blade 394 to engage with the s 'iring contacts 395. 396. The lobe 407 i so formed that the conducting blade ongagen'ient with the spring contacts 393, 394 when the taximeter mechanism is the hired and cash positions and out 111 o f engagement when said mechanism is in the vacant p sition. The construction of the lobe ,ch that the conducting blade 392 is in engagement with the spring contacts 395, 396 when the taximeter mechanism is in the vaca position. and out of engagement when said mechanism is in the hired and cash positions. The operation of the mechanism is as follows: The cam shaft 69 is actuated by the automatic control mechi in and. before described, makes a revolution in three steps to complete the cycle of the taxiineter mechanism thereby setting said 1; meter mechanism in its successive posi tions, namely. Hired, Cash and Vacant. As shown in Fig. 23, the mechanism is in the "vacant position. In this position the conduct' blade 392 is in engagement with the sprint: contacts 396 thus closing the circuit ot the w es 403. 405 which energizes the bulbs 160, 161 of the modified form of indicatm. Fig. 11. thereby illuminating said bulbs and causing the word Vacant to appear in third of a revolution. This action causes the lobe 408 of the cam 380 to turn out of the path of the roller 378 and hence the spring 382 swings the lever 372 in a counter-clockwise direction, thus disengaging the conducting blade 392 from the spring contacts 395, 396, ther l Y breaking the circuit of the Wires 403, 405 h extinguishes the bulbs 160, 161 and causes the epcin. (IS 132, 134 of the indicator. Sirnrltanet with this action, the lobe 407 of the cam 379 throws the roller 377 out of its path thereby vibrating the lever 371 in a clockwise direction which throws the conducting strip 391 into engagement with the spring contacts 393, 394, hence closing the circuit of the wires 403, 404 and causing the bulbs 168. 169 to be illuminated and the word Hired to appear in the openings 133, 135 of the indicator shown in Fig. 11. Therefore, with the taximeter in the hired position, it is evident that the indicator also shows hired, thereby informing persons at a distance of the condition of the taxicab or conveyance upon which said taXimeter and indicator are mounted. The next operation of the automatic control sets the taximeter mechanism in the cash or temporary nonrecording position and rotates the cam shaft 269 another onethird of a revolution. During this one-third of a revolution it can be seen that the roller 377 will remain on the lobe 407 of the cam 379 thus leaving the lever 371 in the same position as the hired position, and hence the word Hired will still show in the indicator. In a like manner the roller 378 will remain in engagement with the low part of the cam 380 and the circuit of the wires 403, 405 will. remain broken and hence the openings 132. 134 of the indicator will remain blank. The third operation of the automatic control sets the taximeter mechanism in the vacant or non-recording position and rotates the cam shaft 269 one third of a revolution to the position as shown in Fig. 23. As the cams 379, 380 turn this onethird revolution, the roller 377 drops off the lobe 407 of the cam 379 and the lever 371 is rotated in counter-clockwise direction under impulsion of the spring 381 thereby disengaging the conducting blade 391 from the spring contacts 393, 394 which breaks the circuit of the wires, 403. 404, and causes the lights 168, 169, of the indicator to be extinguished and the word Hired to disappear from the openings 133, 135. Simultaneously, the lobe 408 of the cam 380 throws the roller 378 out of its path thereby swinging the lever 372 in a clockwise direction. thus again ging the conducting blade 392 with the V contacts 396 and closing the cirofthe wires 403, 405, which again il- -iinutes the bulbs 160, 161 and again causes the word Vacant to appear in the openings 132, 134 of the indicator, informing those interested that the taxicab is for hire. As the control of the indicator in each embodi- 11163013 0]? the invention is governed from the automatic control mechanism, it is obvious that at no time will the driver of the taxicab time tamper with the indicator by operating the lock.

The wires for controlling the operation of the modified form of indicator are led from the taximeter by the plug switch 410 shown in 25., The construction of the plug switch 410 is similar to the plug switch 330 shown in FigsL20, 21 and 26 but contains only three contact members instead of four. Said 7 plug switch consists essentially of the female insulation member 411 mounted between the main plate 250 and the clock mechanism plate 332 and the male insulation member 412 which extends in the opening 344 of the taximeter case 335. The female insulation member 411 has fixed therein the electrical contacts 413, 414, 415 which are slidably engaged with. the electrical contacts 416, 417, 418 mounted in the male insulation member 412. As in the plug switch 330, the plug switch 410 has the electrical contacts 414, 415 spaced further apart than the contacts 413,414, thus preventing improper engagement of the male and female insulation members when installing the same. The electrical contacts 413, 414, 415 have secured thereto, respectively, the wires 404,316, 405 which have been heretofore described and tothe electrical contacts 416, 417,418 are affixed the wires 419,

420, 421 which are clamped to the male insulation member 412 by an insulation strip 422, thus preventing accidental disengagement of said wire from said electrical contacts. The wires 419, 420, 421 are led from the male insulation member 412 through tamper proof means to a remote source, the construction of said means being like those shown in Figs. and 21 incorporating the elbow 350'and the tubular member 353. It is therefore obvious that the wires 419, 420, 421 are free from molestation, thereby preventing the driver or otherimproper parties from tampering with said wires and hence interfering with the, operation of the indicator.

a Wiring diagram for rotary indicator.

' In the wiring diagram, Fig. 8.; the parts of the various mechanism, heretofore described, which are essential for the control and operation of the various electrical devices, are shown diagrammatically and have the same identification numbers, in which a source of electrical energy,-a battery 430, is connected to wire 346 which is led through the conacts 342, 338 of the plug connection 330to the wire 290 in the interior of the taxiineter, and to a wire 431 which is led through a plug connection 433 to the wire 96 in the interior of the rotary indicator. The wire 290 is connected to the common bus 289 from which extends the wire 316 of the key switch. The key switch is shown in the closed position and, therefore, its conducting blade 312 ,completes the lrcuit between the wires 316 and 315. The wire 315 connects through the'convtacts 339, 343 to the wire 31'? outside of the taximeter which in turn, through a plug connection 432 joins with a wire 95 inside the indicator. The wire 95 is attached to the bulb 94 and the wire 88, joined to the wire 95. is attached to the buib 87. The other side of the bulb 94 is connected to the wire 96 to which is fastened the wire89 joining the other side of the bulb 87. A complete circuit thus effected and the bulbs 87, 94 are illuminated. This circuit is completed as follows: The current from the battery 430 flows through the wire 346, the contacts 342, 338,

the wire 290, the bus 289, the wire 316, the

conducting blade 312, the wire 315, the contacts 339, 343, the wire 34?, the plug connection 432, the wire the bulbs 87, 94, the wire 96, plug connec ion 433, the wire 431 and hence back into the battery 430. It can be seen that if the conducting blade 312 is disengaged from the spring contacts 313, 314 by turning the key switch, the circuit just described is broken as the wires'315. 316 are disconnected and hen the bulbs 87, 94 would be extinguished. In this manner, the owner or operator f the taxicab having possession of the key for the key witch has complete control over the functioning of the lights 87, 94 of the indicator.

The other wire 46 of said magnetis connected to the wire 344 outside of the indicator by a plug connection 435. The wire 344 through the contacts 340, 336, is oined to the wire 291 inside the taximeter which in turn is fastened to the spring contact 281. The other spring contact 282 is attached to the bus 289 thereby connecting said spring contact to the battery 430 thron i the wire 290, the contacts 338, and the wire 34 Thus, when the conducting blade 258 of the lever 253 is thrown into eng ement with the spring contacts281, 282, a c cuit is he magnet 20 is energized, KIL 'TQCiH.
